Abstract: A dissolvable urinal splash guard positionable into a bowl of a urinal includes a splash guard assembly including a base having a top and a bottom, wherein the base is at least partially defined by a periphery therearound. A discharge assembly has a discharge aperture formed through a portion of the base. A support assembly including at least one support member is attached to the base and is operative with a drain of the urinal to maintain the dissolvable urinal splash guard in an operative position above the bowl of the urinal during use. At least one of the splash guard assembly, the discharge assembly, or the support assembly is constructed of a material which dissolves in liquid and comprises at least one cleansing agent which is released into a drain pipe of the urinal upon dissolving to help prevent buildup and reduce odors.
